Tado EU Wireless Receiver or Extension Kit

I've got a Vaillant EcoTEC Pro 28 combi boiler which uses eBus but not OpenTherm - I know the latest UK wireless starter pack comes with a wireless receiver that doesn't support digital communication.

Would it be better to purchase a now discontinued extension kit or source an EU version of the wireless starter kit and just swap out the EU plug? If it's the latter does anyone know of anywhere that's selling them?

Don't know if I'm just not typing the right words in but I'm getting next to no results when trying to find an EU version online.
